Effect:_
A strong El Niño is often associated with wet winters over the southeastern US, as well as drought in Indonesia and Australia. Keep in mind that you aren't guaranteed these effects even though there is an El Niño going on; but the El Niño does make these effects more likely to happen.

El Niño is a climate cycle in the Pacific Ocean with a global impact on weather patterns.
El Niño is a climate cycle in the Pacific Ocean with a global impact on weather patterns.

The cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America. Normally, this warm water pools near Indonesia and the Philippines. During an El Niño, the Pacific's warmest surface waters sit offshore of northwestern South America.

Forecasters declare an official El Niño when they see both ocean temperatures and rainfall from storms veer to the east. Experts also look for prevailing trade winds to weaken and even reverse direction during the El Niño climate phenomenon. These changes set up a feedback loop between the atmosphere and the ocean that boosts El Niño conditions. The El Niño forecast for 2015 is expected to be one of the strongest on record, according to Mike Halpert, the deputy director of the Climate Prediction Center, part of the National Oceanic and Atmospheric Administration.

"We don't want to see just the warming in the ocean. We want to see the atmosphere above the ocean respond to the changes," said Michelle L'Heureux, a climate scientist and lead for the El Niño forecasting team at the Climate Prediction Center.

The location of tropical storms shifts eastward during an El Niño because atmospheric moisture is fuel for thunderstorms, and the greatest amount of evaporation takes place above the ocean's warmest water.
